CVE-2025-7299

Code execution via malformed DWG parsing

Published Jul 21, 2025 · Updated Jul 22, 2025

Memory corruption in IrfanView CADImage Plugin 4.70.0.0 allows remote attackers to execute code by opening a crafted DWG file. The DWG parser fails to validate user-supplied file data before memory operations, producing memory corruption in the current process. Exploitation requires the target to visit a malicious page or open a malicious file, and resulting code runs with the current process's privileges.
